Prosecutors said the shooting was a hate-crime and that Ricci was affiliated with a neo-Nazi group, the Associated Press reported.

Ricci's first trial ended with a mistrial, after a witness revealed Ricci previously had served prison time.

The driver in the shooting, Aaron Levi Schmidt, pleaded guilty to charges in connection with the shooting. He already was serving 11 years in prison at the time of the plea for assisting in a criminal gang, officials said.
